Maestro Fuzz Tone FZ-1A

You may want to try your PNP trannies that have a little bit of leakage to get this going. I've been pondering the best solution for powering this off a daisy chain, and I'm open to suggestions. You could use a charge pump and diodes in series to drop the voltage, but that's a bit of a complicated solution. Does anyone have a 1.5V regulator that they suggest?

I prefer to use my FZ-1A with humbuckers. Low output single coils don't get a very saturated fuzz

Voltage dividers can be unstable when the current draw shifts though, and the attack control on this pedal is a bias control which I think may alter the current draw. I've read that it's not an idea solution, but I'm not an expert on that.

I would like to find a simple regulator that I could pair up with an inverter to power this, but after all that the diode option may be looking cheaper anyway

For the daisy-chained power issue, couldn't you borrow the power scheme from the Roger Mayer Page fuzz? IIRC, uses an opamp to invert and limit voltage supplied to the Maestro/Tonebender derived part of the circuit.

It sounds less gated than I expected, but that probably has something to do with the SFT323s. They have about 200 hfe and a lot of leakage. It is not boxed yet, the transistors are in sockets, and I tested it with single coils. So I am going to try some other PNPs and humbuckers to see what sounds best.

I'm working on fz-1 .used a little module which is an adjustable step down regulator .I'm getting -3 volt. but it's not working for me. tried to audio probe it. after the input 100k resistor I get lots of noise and a weak signal.I changed the resistor.and the 10n cap after it and checked for shorts between lines with a multimeter. no luck yet.veryconfused now.there is audio signal at first transistor collector where there is -3 volt. any help please

I built this and an FZ-1. Sounds great but I still need to experiment with transistors. One problem I am having, with this and the FZ-1, is if I have the fuzz pot below 12 oclock the volume cuts in and out, like a leslie speaker. Why would this be?
